FWKNOP for Android
Max Kastanas <max2idea@users.sourceforge.net>
Based on fwknop C implementation by Damien Stuart
===============================================================================
1. Requirements:
a. Apache Ant (1.7.1)
http://ant.apache.org/bindownload.cgi
b. Android NDK (Android r5-linux)
http://developer.android.com/sdk/ndk/index.html
Unzip the contents under a directory ie:
/home/yourname/tools/android-sdk-linux_86
c. Android SDK (Android r08-linux)
http://developer.android.com/sdk/index.html
Unzip the contents under a directory ie:
/home/yourname/tools/android-ndk-r5
d. Include the Android SDK tools directory in your user PATH variable:
export PATH=$PATH:/home/dev/tools/android-sdk-linux_86/tools:/home/yourname/tools/android-ndk-r5
e. Download an SDK Android platform, in a command shell type: "android &"
to start up the "Android SDK and AVD Manager". Download an SDK
platform (Android 2.1 and above is recommended) under the
"Available Packages" section.
f. Java SDK (1.6 and above)
http://www.oracle.com/technetwork/java/javase/downloads/index.html
g. Netbeans (6.9 and above) - Optional if you want to use Netbeans as
the IDE:
http://netbeans.org/downloads/
h. Netbeans Android plugin (0.11 and above) - Optional if you are using
the Netbeans IDE:
http://kenai.com/projects/nbandroid/pages/Install
===============================================================================
2. Setup
a. Untar the tar.gz file:
tar -zxf fwknop-2.0.4.tar.gz
b. Update the properties files with the path to the sdk and ndk tools:
.../fwknop-android/project/build.properties
sdk.dir=/home/yourname/tools/android-sdk-linux_86
ndk.dir=/home/yourname/tools/android-ndk-r5
If you are running Android-4.1.2 or later, then these paths should look
more like:
sdk.dir=/home/yourname/tools/android-sdk-linux
ndk.dir=/home/yourname/tools/android-ndk-r8b
c. Include the Android SDK platform directory in your user PATH variable
export PATH=$PATH:/home/yourname/tools/android-sdk-linux_86/platforms-tools
For Android-4.1.2:
export PATH=$PATH:/home/yourname/android-sdk-linux/tools: \
/home/yourname/android-ndk-r8b:/home/yourname/android-sdk-linux/platform-tools
d. Create a new Android device, in a command shell type: "android".
This will start the android SDK and AVD Manager
Under Virtual Devices create an AVD device and name it as "Android2.1"
For Android-4.1.2 name the new AVD device "Android_fwknop"
e. Update (if needed) project file with the right virtual device as above:
.../fwknop-android/project/nbproject/project.properties
platform.active=Android2.1
For Android-4.1.2 use the .../fwknop-android/project/nbproject/project-4.1.2.properties
file (you might want to replace the project.properties file with this it).
Also for Android-4.1.2 users, you will probably want to replace the
build.properties file with the build-4.1.2.properties file.
f. The relevant fwknop android C code can be found under the
".../project/jni" directory:
1. The ".../project/jni/libfwknop" directory should contain all of
the .c and .h files from the main fwknop/lib/ directory (the
libfko source files. You can copy all of the *.[ch] files from
.../fwknop.../lib manually, or use the "get_libfko_files.sh"
script.
2. The ".../project/jni/fwknop" directory contains the code for
the android-specific client code (with the Java Native Interface
hooks).
===============================================================================
3. Build
a. To build the app make sure you're under the project directory:
$> cd /home/yourname/.../fwknop-android/project
b. To build the application type:
$> ant jar
===============================================================================
4. Run
a. Now search under the .../fwknop-android/dist directory for a .apk
file. You can copy the .apk file to your SD card by typing (make
sure the Android Emulator is on):
$> adb push Fwknop.apk /sdcard/
Then you can open it and install it from within your Android device
using a Filemanager like Astro. Make sure that you have turned on the
"Unknown Sources" Option under Application settings.
===============================================================================
5. Android Emulator
If you don't have a device you can install and run Fwknop in the Android
emulator. To do so follow these steps:
$> android
Under the virtual devices find your device "Android2.1" and start it up
In a command line type:
$> adb install Fwknop.apk
You can now find the Firewall Knock Operator app under the menu tap on
the icon to get started.
===============================================================================
6. Developing with Netbeans
To develop and build with Netbeans make sure you have installed the nbandroid
plugin (see requirements. Once you have that install a new Java platform under
the Tool -> Java Platforms and choose a Google Android platform, navigate
under the SDK platform directory you downloaded under step 1e. Finally, just
open the .../fwknop-android/project directory as a Netbeans project.
===============================================================================
7. Debugging
You can use gdb to debug the app. Before you do so make sure you have the
following attribute in your AndroidManifest.xml file:
android:debuggable="true"
Now rebuild the application and start the Android Emulator, then in a command
shell type:
$> ndk-gdb --project=<path-to>/android/project
This will start gdb in remote debugging, similarly you can follow the same
steps to debug a physical device
